[求助]金宝200S血透机故障

请教：金宝200S血透机开机后面板上时间显示从0.15开始倒计时，当倒计时到0.09时立刻又回到0.15开始倒计时，至0.09，如此重复上述。显示屏上显示故障代码：ERROR! RESTART OR CALL SERVICE ADC 4.01 009。

FM AD function. (CPU F). ADC INTR 001 = A/D timer load counter error call from interrupt state. ADC INTR 002 = A/D timer mode load hold register test error call from interrupt state.

FCN 4.01 005 = AD buffer full. FCN 4.01 006 = AD buffer full and empty.

FM CPU板A/D转换的问题，检查下板上的接头，看下是否有液体溅到板上面。不行的话还是得找厂家工程师支持。

谢谢指点！我明天去医院看看。

ADC 4.01 0xx = More than 20% over range on channel xx Channel xx Explanation 09 HIGH PRESSURE GUARD (HPG)，检查一下HPG压力传感器，还不行的话，再分析。

谢谢大家，是压力传感器坏了。
